Sending Full Credit Card Numbers via API

By default, you cannot send full credit card numbers via the Helcim API.

Not being able to send full credit card numbers benefits your business by limiting your security scope and the potential for exposures due to security breaches or hackers.

Helcim does have a number of tools that will allow you to retain full control over your payment experience. You can also use the tools in your account, like Helcim.js, to allow customers to remain on your website or app.

For more information on the role that card tokenization plays in helping to reduce your security scope and PCI compliance requirements, please visit our support article here.


We do grant exceptions for merchants who can provide a PCI-DSS Attestation of Compliance (AoC) completed by a third-party QSA. You can contact us at [email protected] with your AoC to request the exception.
